The cleanup command should wait for the starboard namespace termination

[danielpacak]

Describe the problem/challenge you have

The starboard cleanup command sends a request to Kubernetes API, but does not wait for the starboard namespace termination.

For example, running $ starboard init immediately after $ starboard cleanup might fail.

Describe the solution you'd like

The command should exit only if the underlying namespace is terminated

Environment:

• Starboard version (use starboard version): 0.2.6
• Kubernetes version (use kubectl version): Any
• OS (macOS 10.15, Windows 10, Ubuntu 19.10 etc): Any
